CO2 Capture Analysis of Tobacco Biochar-AlCl3 Composite
CO2 Capture Analysis of Tobacco Biochar-AlCl3 Composite
In this study, the performance of tobacco biochar-AlCl3 composite for CO2 capture was investigated. Biochar-AlCl3 composites were prepared at different blend ratios (10:0.4; 10:2; 10:4, wt./wt.) and used for CO2 capture experiments to determine the optimal Al metal content at which CO2 adsorption was highest. Biochar composites were produced through slow pyrolysis under inert nitrogen atmosphere in a fixed bed reactor at 600oC for 3h. Properties of biochar-metal composites and raw biochar samples were characterized with SEM-EDS, XRD and FTIR analysis. CO2 experiments were conducted in TGA under N2 atmosphere with a flow rate of 50 ml/min at 25°C. The maximum CO2 adsorption was observed as 59.97 mg/g for biochar: AlCl3 composite at a ratio of 10:2. Finally, results of study showed that biochar-AlCl3 composites have great potential as a CO2 capture material due to its low-cost, sustainability and CO2 capture capacity.
